CR Series with SmartCast® PoE Technology
CR24™ 2' x 4' Architectural LED Troffer
Product Description
BETTER LIGHTING AND BIGGER SAVINGS.
SmartCast® Power over Ethernet (PoE) provides beautiful, comfortable and adaptive illumination
with greatly simplified lighting controls. You’ll cut energy costs up to 70 percent while saving money,
improving aesthetics, lowering TCO and making your entire enterprise more productive.
SO SIMPLE IT JUST WORKS.
SmartCast® PoE cuts out steps and components when compared to ordinary lighting controls. That
means less time and money spent designing, wiring, installing and commissioning your lighting project.
And you can commission one fixture to hundreds in a single step.
READY FOR WHAT’S NEXT.
SmartCast® platform PoE is enabled to securely connect with building management systems,
enterprise-wide networks and the Internet. Built on a future-ready open platform with a standardsbased API, the sky’s the limit for third-party cloud-based applications.

Product Specifications
CREE PoE TECHNOLOGY
Cree SmartCast® PoE technology seamlessly integrates hardware, software
and the user experience into an intuitively simple and powerful lighting
intelligence platform that saves time, money and up to 70% on energy. It
eliminates the challenges of ordinary PoE lighting by automating the initial
setup up of the platform and can commission hundreds of devices with the
push of one button. It is open, scalable, secure and enables the Internet of
Things for buildings.
CREE TRUEWHITE® TECHNOLOGY
A revolutionary way to generate high-quality white light, Cree TrueWhite® Technology is
a patented approach that delivers an exclusive combination of 90+ CRI, beautiful light
characteristics, and lifelong color consistency, all while maintaining high luminous
efficacy – a true no compromise solution.
POWER OVER ETHERNET INFRASTRUCTURE (BY OTHERS)
• Delivers power and data to the luminaires with one cable from PoE
switch port to luminaire
• uPoE recommended to enable full fixture output
• Category 5e or 6a cables, shielded or unshielded. Finalize selection with
infrastructure provider based on run length or other installation details
• Recommended network switches are Cisco Catalyst 4506-E,
WS-C3850-24U-S, WS-C3850-48U-S
Reference Cree.com/smartcast for future additions to the compatibility
list
EMBEDDED INTELLIGENCE AND PLATFORM FIRMWARE
• Twin microprocessors and flash memory with bundled SmartCast
platform firmware
• Luminaire negotiates with switch to determine maximum lumen output
• uPoE = 4,000 lumens
• Network switch and luminaire communicate to prevent power from
being delivered on miswired cables protecting the luminaire
• Light operates at full power output when initially connected to a
compatible and configured Power over Ethernet switch
• SmartCast Manager PC Application
(https://www.creelink.com/search?qv=1&docid=8878) is used for
One Button™ Setup of hundreds of devices at one time
• Creates lighting network
• Utilizes visual light communication and platform algorithms to
create logical groups
• Daylight calibration
• All settings are stored in device flash memory
• Task tuning available through SmartCast Manager
ROOM-SIDE HEAT SINK
An innovative thermal management system designed to maximize cooling
effectiveness by integrating a unique room-side heat sink into the diffusing lens. This
breakthrough design creates a pleasing architectural aesthetic while conducting heat
away from LEDs in a temperature-controlled environment. This enables the LEDs
to consistently run cooler, providing significant boosts to lifetime, efficacy, and color
consistency.
CONSTRUCTION & MATERIALS
• Durable 22-gauge steel housing with standard troffer access plate for electrical
installation
• One-piece lower reflector finished with a textured high reflectance white polyester
powder coating creates a comfortable visual transition from the lens to the ceiling
plane
• Includes t-bar clips and holes for mounting support wires (by others)
OPTICAL SYSTEM
• Unique combination of reflective and refractive optical components achieves a
uniform, comfortable appearance while eliminating pixelation and color fringing
• Components work together to optimize distribution, balancing the delivery of high
illuminance levels on horizontal surfaces with an ideal amount of light on walls
and vertical surfaces. This increases the perception of spaciousness
• Diffusing lens integrated with upward-facing LED strip eliminates direct view of
LEDs while lower reflector balances brightness of lens with the ceiling to create a
low-glare high angle appearance
ELECTRICAL SYSTEM
• Integral, high-efficiency driver
• Operating Temperature Range: 0˚C - + 35˚C (32˚F - + 95˚F)
• Dimming: 5% - 100%
• Standby Power: <1.0W
REGULATORY & VOLUNTARY QUALIFICATIONS
• cULus Listed
• Suitable for damp locations
INTEGRAL MOTION SENSOR
• Passive infrared (PIR)
• Designed for indoor use
• Coverage area: 100 sq. ft. (30.5m2) at 10 ft. (3.0m) mounting height
• Not intended to be mounted higher than 12 ft. (3.7m)
• RoHS compliant. Consult factory for additional details
• Meets FCC Part 15, Subpart B, standards for conducted and radiated emissions
• Operation:
•Grouped with a wall control: Luminaire will operate in vacancy mode
(manual-on/auto-off)
•Not grouped with a wall control: Luminare will operate in occupancy
mode (auto-on/auto-off)
• Occupancy group and other settings adjustments available through
SmartCast Manager
AMBIENT LIGHT SENSOR
• Sensor response matches response of human eye
• Not intended to be mounted higher than 12 ft. (3.7m)
• Automatic daylight calibration during One Button™ Setup
• Luminaires adjust for daylight independently to maximize savings
FUTURE ENABLEMENT
• Firmware updates are available over the network for future function and
feature improvements

Photometry
CR24-40L-30K BASED ON CESTL REPORT TEST #: 2013-0009
Luminaire photometry has been conducted by a NVLAP accredited testing laboratory in accordance with IESNA LM-79-08. IESNA LM-79-08 specifies the entire luminaire as the source
resulting in a luminaire efficiency of 100%.
